fixed that the inside of the housing had to be separated An outwardly directed rabbit was punched into the bottom edge, which protruded into a notch in the inner circumference of the watch case, thus preventing the unpleasant twisting of the bottom of the case prevented after its onset. However, this definition of the floor requires a relatively large floor punch piece for punching out the additional rabbit, which is associated with considerable material loss, finally It was not uncommon for the internal thread of the middle part of the watch case to be damaged when the notch was milled out or · due to the interrupted thread turn when the screw ring is later screwed in and unscrewed to · another The disadvantage of the known embodiments was often that that the movement holder ring supporting the movement with dial only because of the weak movement retaining ring and middle part of the watch case penetrating winding shaft was prevented from rotating, or that the movement retaining ring attached dial are pressed so strongly against the upper protruding edge of the clock housing middle part it had to be that, due to the great heat resistance, ε would arise Twisting was made impossible.

All of these Bach parts are now through see each time in the waterproof watch case of the present! Corresponding designs of the inner circumference of the vertical one that no longer form a closed circle

which in a notch in the inner circumference of the middle part of the housing that directly accommodates this leu of the movement retaining ring ε intervenes.

An embodiment of the present heating is shown schematically and partially in section in the drawing, namely shows

Fig. 1 a side view of the watch case with movement retaining ring, sealing ring, base and screw ring in section along the line I-1 of Fig. %

Fig. 2 is a side view without a sealing ring and without a base and screw ring in section along the line II-II of Fig. 4 »

Fig. 3 the bottom view of the watch case according to Fig. 1, but without attached screw ring and

Fig. 4 the bottom view of the watch case according to Fig. 2.

The watch case consists of the middle part 4j the Movement retaining ring 1, the sealing ring 7, the bottom 9 and the Screw ring 12. The latter (12) is screwed onto the housing middle part 4 by means of thread 13 and then presses the inwardly offset edge 8 of the bottom 9 against the sealing ring 7 »the other hand of the recess 5 of the Housing middle part 4 and the recess 6 of the work ring rests. This (1) has an annular extension 14 » which on the inward protruding and in his

Recess 16 the watch glass receiving hand 15 of the middle part of the case 4 hires.

The bottom 9 ″ has its attached to the vertical wall Banding 8 has an indentation 10 which engages in a recess 11 in the lower part of the movement holder ring 1 Material pushed out so that no additional material, as for example for Ausstang; en a hare "required will. Of course, the impression 10 can be in contrast for the graphic representation in abbot, 3 also made so that it "cannot be seen from below when looking at the watch case, but the circular one The shoulder edge 17 of the base 9 rests evenly on the attached screw ring 12 (see Figure 1)

The movement holder ring 1 ″, in turn, has on its upper one Rope an outwardly protruding lawn 2, which in a notch 3 cLes inner circumference of this rope of the work he holds inge s 1 receiving center housing part 4 engages.

The mentioned recess 11 and the protruding rabbit 2 on the movement holder ring 1 are preferably opposite one another, as is shown in Figs. 1 and 2 or 3 and 4 of the drawing.
